OneTile Mahjong — The One-Tile Tenpai Puzzle

One hand. One choice. One tile.

OneTile Mahjong is a pure logic puzzle built around a single elegant mahjong idea: tenpai. You're dealt 14 tiles, and exactly one of them — when discarded — leaves your remaining 13 just one tile away from a complete winning hand. Your job is to find that tile.

No dice, no luck, no opponents. Just you, the tiles, and the quiet satisfaction of seeing the pattern click into place. Long-press any tile to preview your waits, use the built-in Tenpai Lab to study the hand, and tap a hint when you're truly stuck.

Progress through hand-crafted levels rated 1 to 3, build your solve streak, and come back each day for a fixed Daily Challenge that's the same for everyone. Track your best streak and completion stats as you sharpen your reading.

Whether you're a seasoned mahjong player or completely new to the game, OneTile mahjong teaches you to see tenpai.
